Question

Construct context-free grammars that generate the given set of strings. If the grammar has more than one variable, we will ask to write a sentence describing what sets of strings expect each variable in the grammar to generate. For example, if the grammar was:

SE O O- EC

I could say "C generates binary strings of length one, E generates (non-empty) even length binary strings, and O generates odd length binary strings." It is also fine to use a regular expression, rather than English, to describe the strings generated by a variable (assuming such a regular expression exists).

1) {0 m1 n0 n+2m : m, n ≥ 0}
